2011-09-07gc: add -p flag to catch import cycles earlierRuss Cox
The linker would catch them if gc succeeded, but too often the cycle manifests as making the current package and the imported copy of itself appear as different packages, which result in type signature mismatches that confuse users. As a crutch, add the -p flag to say 'if you see an import of this package, give up early'. Results in messages like (during gotest in sort): export_test.go:7: import "sort" while compiling that package (import cycle) export_test.go:7: import "container/heap": package depends on "sort" (import cycle) Fixes #2042.

2011-09-07exp/regexp: bug fixes and RE2 testsRuss Cox
Also add exp/regexp to build (forgot before). At this point I am very confident in exp/regexp's behavior. It should be usable as a drop-in replacement for regexp now. Later CLs could introduce a CompilePOSIX to get at traditional POSIX ``extended regular expressions'' as in egrep and also an re.MatchLongest method to change the matching mode to leftmost longest instead of leftmost first. On the other hand, I expect very few people to use either. R=r, r, gustavo CC=golang-dev https://golang.org/cl/4990041
2011-09-07net: ParseCIDR returns IPNet instead of IPMaskMikio Hara
Note that this CL will break your existing code which uses ParseCIDR. This CL changes ParseCIDR("172.16.253.121/28") to return the IP address "172.16.253.121", the network implied by the network number "172.16.253.112" and mask "255.255.255.240".

2011-09-06url: handle ; in ParseQueryRuss Cox
Most web frameworks allow ; as a synonym for &, following a recommendation in some versions of the HTML specification. Do the same. Remove overuse of Split. Move ParseQuery tests from package http to package url. Fixes #2210. R=golang-dev, r CC=golang-dev https://golang.org/cl/4973062
2011-09-06gc: unify stack frame layoutRuss Cox
allocparams + tempname + compactframe all knew about how to place stack variables. Now only compactframe, renamed to allocauto, does the work. Until the last minute, each PAUTO variable is in its own space and has xoffset == 0. This might break 5g. I get failures in concurrent code running under qemu and I can't tell whether it's 5g's fault or qemu's. We'll see what the real ARM builders say. R=ken2 CC=golang-dev https://golang.org/cl/4973057

2011-09-03gofix: do not convert url in field namesGustavo Niemeyer
There's some ambiguity in the U{url: url} case as it could be both a map or a struct literal, but given context it's more likely a struct, so U{url: url_} rather than U{url_: url_}. At least that was the case for me. R=golang-dev, rsc, adg CC=golang-dev https://golang.org/cl/4972052

2011-09-02exp/norm: added Reader and Writer and bug fixes to support these.Marcel van Lohuizen
Needed to ensure that finding the last boundary does not result in O(n^2)-like behavior. Now prevents lookbacks beyond 31 characters across the board (starter + 30 non-starters). composition.go: - maxCombiningCharacters now means exactly that. - Bug fix. - Small performance improvement/ made code consistent with other code. forminfo.go: - Bug fix: ccc needs to be 0 for inert runes. normalize.go: - A few bug fixes. - Limit the amount of combining characters considered in FirstBoundary. - Ditto for LastBoundary. - Changed semantics of LastBoundary to not consider trailing illegal runes a boundary as long as adding bytes might still make them legal. trie.go: - As utf8.UTFMax is 4, we should treat UTF-8 encodings of size 5 or greater as illegal. This has no impact on the normalization process, but it prevents buffer overflows where we expect at most UTFMax bytes. R=r CC=golang-dev https://golang.org/cl/4963041

2011-09-01gc: fix label recursion bugsRuss Cox
Was keeping a pointer to the labeled statement in n->right, which meant that generic traversals of the tree visited it twice. That combined with aggressive flattening of the block structure when possible during parsing meant that the kinds of label: code label: code label: code sequences generated by yacc were giving the recursion 2ⁿ paths through the program.
